"He sacrificed his life to save others"
Sacrificing one's life to save others marks the most sublime message in Christianity. This is the crux of Christianity which calls for extending a helping hand to the needy even at the expense of making personal sacrifices.
The Holy Bible includes numerous verses that call for extending all possible efforts to help others. One of them is “Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God,” (Hebrews 13:16)
